Application: Controlled flow in one direction, free flow in opposite direction. 200 PSI pressure drop is required for pressure compensation.
Maximum Flow Rate: 10 GPM.
Maximum Operating Pressure: 5000 PSI (CAUTION: Pressures over 3000 PSI require steel housing).
Temperature Range: -40°F to 248°F (Extreme Limits).
Recommended Filtration Level: ISO 4406 Cleanliness Level 18/16/13 or cleaner.
Cartridge: Model FAR1-10-* , sold separately.

Eaton Vickers® FR2-16 Series
2-Port Pressure Compensated flow control valves
For Hydraulic Service To 30 GPM
              
Features: Cartridge style (Requires a machined cavity or housing for installation). Pressure compensated for accurate flow control regardless of changes in input or load pressure.
Application: Controlled flow in one direction only. Valves will start to control flow at 60 to 70 PSI pressure drop.
Maximum Flow Rate: 30 GPM.
Maximum Operating Pressure: 3000 PSI.
Temperature Range: -40°F to 248°F (Extreme Limits).

Eaton Vickers® PFR2-10 Series
3-Port Pressure Compensated Priority flow control valves
For Hydraulic Service To 10 GPM Regulated
         
Features: Cartridge style (Requires a machined cavity or housing for installation). The flow adjustment range is from the factory set maximum flow rate down to 50% of that rate. Pressure compensated for accurate flow control regardless of changes in input or load pressure.
Application: This valve maintains a constant priority flow from port 1 to port 3 based on the setting adjustment, regardless of pressure changes downstream on port 3. Flow in excess of the priority setting is directed to port 2. If the priority flow at port 3 is blocked, the spool will shift to satisfy the priority flow requirement, thereby closing off flow to port 2.
Maximum Flow Rate: 15 GPM (Inlet), 10 GPM (Priority).
Maximum Operating Pressure: 3000 PSI.
Temperature Range: -40°F to 248°F (Extreme Limits).
Recommended Filtration Level: ISO 4406 Cleanliness Level 18/16/13 or cleaner.
Cartridge: Model PFR2-10*, sold separately.
Housing: Cavity size C-10-3, sold separately.

 

Brand Hydraulics FC51 Series
3-Port Pressure Compensated Priority flow control valves
For Hydraulic Service To 90 GPM
         
Features: Precision ground chrome plated spool for long life. Diamond honed spool bore provides consistent spool fit with low leakage. Every valve is factory tested for shutoff, linearity, max. flow & pressure compensation.
Application: The FC-51 full range pressure compensating variable flow control is designed so that the orifice area varies as the lever is rotated. Fluid travels past the variable orifice, through the compensator spool and then out the controlled flow port. The flow out of the CF port is proportional to the orifice area which can vary from closed to open. The sum of the controlled flow and the excess flow equal the inlet flow, and as the controlled flow increases the excess flow decreases. Both outlets are pressure compensated by a spool that maintains a constant flow while adjusting for pressure. Hunting between a compensated pump and the valve is dampened with a dashpot on the compensator spool. The FC-51 can be used as a 2-port flow control by plugging the excess flow port, and, for best results, limiting the flow to about 50% of the valve's rated flow.
Materials: Cast iron body. Heat treated spools (Stainless steel available). Buna-N O-Rings (Standard).
Maximum Operating Pressure: 3000 PSI.

 

Brand Hydraulics FCR51 Series
3-Port Pressure Compensated Priority flow control valves
With Relief, For Hydraulic Service To 90 GPM
         
Features: Precision ground chrome plated spool for long life. Diamond honed spool bore provides consistent spool fit with low leakage. Every valve is factory tested for shutoff, linearity, max. flow & pressure compensation. High lift ball spring relief valve.
Application: The FCR-51 full range pressure compensating variable flow control is designed so that the orifice area varies as the lever is rotated. Fluid travels past the variable orifice, through the compensator spool and then out the controlled flow port. The flow out of the CF port is proportional to the orifice area which can vary from closed to open. Once the pressure on the CF port increases above the relief setting, the relief valve opens and diverts flow to the EX port while maintaining pressure on the CF port. The EX port must be plumbed back to tank for the relief to function. The sum of the controlled flow and the excess flow equal the inlet flow, and as the controlled flow increases the excess flow decreases. Both outlets are pressure compensated by a spool that maintains a constant flow while adjusting for pressure. Hunting between a compensated pump and the valve is dampened with a dashpot on the compensator spool.
Materials: Cast iron body. Heat treated spools (Stainless steel available). Buna-N O-Rings (Standard).
Maximum Operating Pressure: 3000 PSI.
